2. Description of Related Art

Mirrors or rear view means, such as those including a camera pod, aretypically exposed to the outside environment when used as a side viewmirror secured to the outside of a vehicle and when used inside avehicle as an internal rear view mirror. Rear view means are typicallymade up of many components which require a number of different assemblyparts and are complicated and expensive to manufacture. In addition,when exposed to the outside environment, rear view means are subject todirt or debris entering within the assembly. In addition, while a rearview means may include improved protection from the outside environmentsuch rear view means fail to provide a full and expansive field of viewincluding a wide angle view as may be desired by a driver for viewingthe driver's blind spot.

European Patent No. 2 492 145 B1 describes an external rear view mirrorwith a mirror head and a mirror base, which are covered with at leastone body element in the form of a body frame, a body cap and a mirrorbase cover, and a mirror glass that is installed rigidly relative to themirror head. The mirror head rests on the mirror base, the body cover ofthe mirror head is composed of multiple pieces of the body frame and thebody cap, and the mirror base is equipped with a mirror base cover,where the body cap has an opening designed for the passage of the mirrorbase and the mirror base cover. The mirror base is rigidly connected toa mirror carrier that carries an electrical glass adjustment drive,where the glass adjustment drive is connected to at least one bodyelement.

Another external rear view mirror assembly for a motor vehicle includesa mirror base or foot provided for arrangement on the motor vehicle anda mirror head arranged on the mirror foot as well as a mirror glassaccommodated in the mirror head and arranged rigidly and fixed nonadjustably with respect thereto. Such an external rear view mirror isdescribed in European Patent No. 2 492 144 B1. At least one articulationis provided between the mirror head and the arrangement of the mirrorfoot on the motor vehicle. The articulation includes a total of twoarticulation axes, and the direction vectors of the articulation axesare independent of each other. The two articulation axes are associated,jointly and/or independently of each other for swiveling the mirror headfrom an operating position to a swung-in position and vice versa. Thearticulation axes are also for swinging-in the mirror head in andagainst the direction of motion, adjusting an individual adjustingposition of the mirror glass by adjusting the mirror head depending on,e.g., the seating position and the height of a driver of the motorvehicle. The mirror has a first adjusting drive driven by an electricmotor and associated to a first articulation axis of the twoarticulation axes and a second adjusting drive driven by an electricmotor and associated to a second articulation axis of the twoarticulation axes.

European Patent No. 2 253 510 B1 describes a rearview assembly with amirror frame, mirror base, mirror housing, mirror glass, and glassactuator assembly. Specifically, it describes a method of improving theconnection between components of the rearview assembly by usingadditional connection means to support a rigid fixture of the bezel atthe mirror frame.

A rear view device for a motor vehicle may include the head section.

In another aspect, a housing section and the lid section tightly sealthe hollow area towards the outside over at least almost the entirecircumference. Due to the fact that the hollow area is surrounded atleast almost over its entire circumference towards the outside, thehollow area is protected against penetration by dirt and humidity. Thismakes it possible to arrange the at least one electronic unit in thehollow area without its own seal. This makes it possible to create acompact design for the head section.

In general, it is feasible to provide the electronic unit with its ownhousing, with which it can be arranged in the hollow area between thehousing section and the lid section. However, it has been shown to beadvantageous when the at least one electronic unit can be arranged or isarranged without housing in the hollow area.

The housing section and the lid section can in general be connected toeach other in any manner required. With one embodiment of the headsection according to the invention, it is provided that the housingsection and the lid section can be locked or are locked relative to eachother at a coupling portion in such a manner that they overlap eachother, and in particular form an undercut. When the lid section and thehousing section form an undercut, it is easily possible to achieve afixed connection of the two components. In particular, in such cases,the housing section and the lid section can be locked to each otherwithout using tools, e.g. by means of clips.

In general, it is feasible to create the coupling portion only insections. Preferably, the coupling portion is designed to surround thecircumference.

It is feasible to make the rear view means relatively mobile in relationto the housing section. This can be the case, for example, when the lidsection and/or the housing section is created at least in sections froma flexible, pliable material, such as a plastic membrane. However, ithas been shown to be advantageous when the rear view means is lockedrelative to the housing section. In such cases, the rear view means canbe set by adjusting the head section.

The rear view means can comprise a component which can be separated oris separated from the lid section. In such cases, the lid section canfor example be adhered, or locked for example by spraying a reflectivecoating on the lid section. In one embodiment of the head sectionaccording to the invention, it is provided, however, that the lidsection and the rear view means comprise a single-piece component.

This makes it possible to reduce the number of components of the headsection.

In general, it is feasible to create the lid section in a disc form.However, it has been shown to be advantageous when the lid section isdesigned as a type of clamp, and comprises a flat portion, which inparticular comprises the rear view means, and at least one edge portionwhich extends transverse or diagonally to the flat portion. In suchcases, the lid section can be locked to the housing section like a clampwith the at least one edge section. The edge section can here beadjacent to the housing section from the inside, or grips the housingsection from the outside.

The housing section and the lid section can be created from any materialrequired. When the lid section and the rear view means include acombined single-piece component, i.e. when the rear view means is partof the lid section, it has been shown to be advantageous when the lidsection comprises a multiple-part component, where the flat portionincludes a first lid part, in particular a plastic part, and the edgeportion comprises a second lid part, in particular a plastic part.

In general, it is feasible that the multiple-part component includes adual-part plastic section. When the lid section has several functions,however, further plastic parts can be provided.

Due to the fact that the edge section can include another plastic part,such as the flat portion, the edge section can be designed to form atight seal. The electronic unit can include a lighting unit for example.The light from the head section generated by the lamp can penetrateoutwards through the light window. In such cases, the electronic unitcan comprise a repeatedly flashing light or lighting for the areaimmediately surrounding a motor vehicle.

With one embodiment of the head section according to the invention, itis provided that the housing section includes a first housing part, inparticular a plastic part, which lies directly on the hollow area andwhich has a coloring which is in particular essentially opaque and/ornon-translucent, wherein the first housing part comprises an opening inthe area of the light window. Due to the fact that the first housingcomponent is opaque and non-translucent, an attractive appearance can beachieved. Due to the fact that an opening is provided in the firsthousing part, the light from the electronic unit can penetrate outwards.

In order to prevent penetration by dirt or humidity, with a furtherdevelopment of the latter inventive embodiment, it is provided that anoptical element, such as an optical fiber and/or light disc, can bearranged in the and/or on the opening of the first housing part of thehousing section and that a housing seal can be arranged or is arrangedbetween the first housing part of the housing section and the opticalelement. Due to the provision of the housing seal between the opticalelement and the opening of the housing section, the hollow area istightly sealed towards the outside. As a result, no separate housing isrequired for the electronic unit.

As a supplement or an alternative to the provision of a housing seal, ithas been shown to be advantageous when a second housing part, inparticular a plastic part, is arranged in such a manner that it lies ona surface of the first housing part which faces away from the hollowarea, and is essentially translucent and/or transparent at least in thearea of the light window. In particular, in the area of the light windowis designed as an optical element such as an optical fiber and/or lightdisc.

Due to the fact that a second housing part is adjacent to the firsthousing part, which in particular covers the opening provided in thefirst housing part towards the outside, no housing seal is required. Dueto the fact that the second housing part is translucent and/ortransparent, light from the electronic unit which is designed as alighting unit can penetrate outwards from the hollow area of the headsection.

The rear view means can comprise a reflective means and/or a displaymeans such as a screen, in particular an LED or LCD screen. When thedisplay means comprises a screen, the screen can be arranged on the flatportion of the lid section. It is furthermore feasible that the lidsection, at least in the portion on which the LED or LCD screen isarranged, is arranged in a transparent and/or translucent manner, andthe screen is arranged on the side of the flat portion of the lidsection which faces towards the hollow area.

The electronic unit may include a setting facility for the rear viewdevice. This makes it possible to set the rear view device in a simplemanner. The setting facility can be arranged on the upper surface of theflat portion of the lid section which faces towards the hollow area.

It has been shown to be advantageous when the setting facility comprisesa setting unit with at least one lighting means which can be locked oris locked relative to a rear view means, and by means of which adirectable or directed light beam can be emitted, which is at leastalmost solely perceivable in a specified operating position by a driverof a motor vehicle and/or a control unit.

The lighting means may include a coiled wire bulb, an LED or a laser.

Due to the fact that the light beam can be detected at least almostsolely in the specified operating position by a driver of a motorvehicle and/or by a control unit, the rear view means is easy to adjustin a position which conforms to the regulations.

In order to enable light to exit, it is advantageous when the housingsection and/or the lid section, in particular the edge portion, includesa transparent and/or translucent area through which the light beamemitted by the lighting means can penetrate outwards at least almostunimpeded.

This makes it possible for light which is emitted by the lighting meansto penetrate outwards from inside the rear view device and to beperceivable from the outside, where in the hollow area of the housing,it is at the same time protected against environmental influences.

The transparent and/or translucent area can in general be designed inany manner required. It is advantageous when the transparent and/ortranslucent area comprises a recess, in particular throughout, and/or atranslucent and/or transparent material such as glass, in particularsmoked glass, or plastic.

In general, it is feasible that the light beam emitted from the lightingmeans is sufficiently bundled in order to be perceivable almost solelyin the specified operating position by the driver of a motor vehicleand/or the control unit. Furthermore, it has been shown to beadvantageous when the setting unit comprises at least one opticalelement which can be functionally assigned or is assigned to thelighting means, with which the light beam emitted by the lighting meanscan at least be bundled.

Furthermore, the object is attained by means of a rear view device, suchas an internal or external mirror for a motor vehicle with at least onehead section, in particular with at least one of the features describedabove.

Finally, the object is attained by means of a motor vehicle with atleast one rear view device with at least one of the features describedabove and/or with at least one head section, in particular with at leastone of the features described above.

The head section according to the invention, the rear view deviceaccording to the invention and the motor vehicle according to theinvention have been shown to be advantageous in many respects.

Due to the fact that the lid section and the housing section surround ahollow area in an almost entirely sealing manner, electronic devices canbe provided in the hollow area which require no housing. As a result,the head section and the rear view device can be compact in design.

In an aspect, an external rear view device for a motor vehicle includesa fixed base assembly provided for arrangement on the motor vehicle, amoveable head assembly attached to the base assembly, an articulationassembly, the articulation assembly including a fixed part attached tothe fixed base assembly and a moveable part attached to the headassembly, and a camera unit immovably secured within at least one of thefixed base assembly or the moveable head assembly, where thearticulation assembly includes two articulation axes, the directionvectors of the articulation axes being independent of each other.

Furthermore, due to the movable mirror head and to provide a consistentfield of view, a camera may be located either within the base assemblyor on a fixed component within the mirror head. The location within thebase provides a greater impact protection. Being positioned within thehead on a fixed component, the camera is directed to view through theglass and/or to view under the mirror through a lens in the lower casingelement where it is protected against environmental influences.

Attached to the lower and upper casing elements, the bezel may carryvarious required legal glass types and provide the final locking systemto control the head assembly retention and alignment of the mirror headcomponents. The bezel may house a number of functions or features suchas lights, warnings or heating elements.

The articulation assembly may be surrounded by an additional bracketmounted to the fixed case frame and a cradle mounted to the lower casingelement allowing rotational movement inboard/outboard and up/down toprovide additional support. In particular, rotational downward load maybe exerted on the mirror head, with a case frame ring acting as theinboard and outboard stops.

In addition, the articulation assembly may also set the mirror head to afold park condition, i.e. the folded position of the mirror when the caris parked, utilising the full range of movement. The articulationassembly can be a single 2 axis actuator or a combination of 2 singleactuators, positioned independently along the mirror rotation axis, withor without intelligences. A separate memory module may be incorporatedas well.

In an aspect, a head assembly of an external rear view device, inparticular in the form of a mirror head of an external rear view mirror,can be articulated inboard/outboard and up/down using an articulationmeans. In particular, the articulation means may be a glass actuator,around a spherical joint, with spherical seats being provided betweenparts moving relative to each other such that they can rotate around twoarticulation axes perpendicular to each other having a common jointpoint. This ensures the maintenance of current end user functionalitywhile offering significant smaller mirror size, with a reduction of sizeup to 30%. In addition, the unique layout of the internal mechanism withits spherical seats enhances packaging and performances.

The articulation assembly may also be supported and protected for impactusing the spherical seats, in particular due to the arrangement of framemeans between the articulation assembly and a casing of the headassembly. Because the casing is assembled from several casing elements,one of which is secured to the moveable part of the articulationassembly, this improves the weight distribution and reduces totalhousing frontal area on the vehicle which in turn improves aeroperformance and, thus, provides a higher fuel efficiency.

The pivot system used for the rear view device of an aspect of theinvention with the single pivot point for two articulation axes permitsa mirror adjustment while providing dynamic mirror performance andmirror impact support.

In a further aspect, a rearview device for a vehicle includes a moveablehead assembly, an actuator assembly comprising a fixed part and amoveable part, the moveable part being attached to the head assembly,and a motor cradle configured to attach the actuator assembly to themoveable head assembly.

The moveable head assembly may include a lower case and the actuatorassembly is attached to the lower case of the moveable head assemblyusing the motor cradle.

The following description refers to a head section for a rear viewdevice to be attached on a motor vehicle as for example described inEuropean Patent No. 2 492 144 B1, European Patent No. 2 492 145 B1, orEuropean Application No. 16198759. Such a head section includes a casingmeans with a housing section and a lid section, at least one electronicunit, and one rear view means. With respect to further details on thehousing section reference is made to U.S. patent application Ser. No.15/000,754.

Referring to FIGS. 1-3, the figures show a head section for a rear viewdevice which is overall assigned reference numeral 2. The 2 can, forexample, include a mirror head of an internal or external mirror. Thehead section 2 includes a housing section 4 and a lid section 6.

FIGS. 1-3 show the head section 2 in a folded out operating position. Inthis position, the housing section 4 essentially faces towards thedirection of driving 8, and the lid section 6 is essentially arrangedfacing away from the direction of driving 8. As can be seen in FIGS. 2and 3, an electronic unit 10 can be arranged between the housing section4 and the lid section 6. This can be locked in a hollow area 12 betweenthe housing section 4 and the lid section 6.

With the exemplary embodiments shown in the figures, a rear view means14 is arranged on the side of the lid section 6 which faces away fromthe hollow area 12, wherein the lid section 6 and the rear view means 14comprise a combined component.

The lid section 6 and the housing section 4 surround the hollow area 12over its full circumference and at least almost completely seal ittightly towards the outside. This makes it possible to arrange theelectronic unit 10 without housing in the hollow area 12.

FIG. 1 shows a first exemplary embodiment in which the lid section 6comprises a flat portion 16 and two edge portions 18 which extenddiagonally to the flat portion 16. The lid section 6 comprises amultiple-part component which is designed as a dual-part injectionmolded element. Here, the flat portion 16 is formed from a first lidpart and the two edge portions 18 are formed from a second lid part. Thetwo edge portions 18 grip the housing section 4 from outside, whereinthey overlap the housing section 4 in a coupling portion 20. Here, theedge portions 18 includes a lid part which acts as a sealing means 22.Furthermore, the sealing means 22 additionally includes a sealingelement which is designed as an 0-ring 24. It should be appreciated thatthe sealing means 22 and sealing element or 0-ring 24 that is positionedbetween the lid section 6 and the housing section 4 may also be used inthe second exemplary embodiment of FIG. 2, the third exemplaryembodiment of FIG. 3, the fourth exemplary embodiment of FIG. 4, thefifth exemplary embodiment of FIG. 5, the sixth exemplary embodiment ofFIG. 6, or the seventh exemplary embodiment of FIG. 7.

FIG. 2 shows a second exemplary embodiment of the head section 2according to the invention. In this embodiment, an electronic unit 10 isarranged in the hollow area 12. In the exemplary embodiment shown inFIG. 2, the electronic unit 10 comprises a printed circuit board 26 anda lamp 28. In order to affix the printed circuit board 26 in the hollowarea 12, a retaining device 28 is provided, which also rests on thehousing section 4. In the exemplary embodiment shown in FIG. 2, thehousing section is formed from a first housing part 30 which is opaqueand non-translucent.

In order to enable light from the lamp 28 to penetrate outwards from thehollow area 12, the first housing part 30 of the housing section 4comprises an opening 32. The opening 32 is part of a light window 34which enables an outward penetration of light from the electronic unit10 which comprises the printed circuit board 26 and the lamp 28 and isdesigned as a lighting unit 36. In order to achieve an attractiveemission of light, an optical element 38 is provided which is arrangedat the opening 32. The optical element 38 can comprise a light fiberand/or a light disc. In order to prevent the penetration of humidity anddirt, a housing seal 40 is arranged between the optical element 38 andthe first housing part 30 of the housing section 4.

FIG. 3 shows a third exemplary embodiment of the head section 2 in whichthe housing section 4 includes a second housing part 42, which isarranged on an outer side which faces away from the hollow area 12 ofthe first housing part 41. The second housing part 42 includes atransparent and/or translucent area, at least in the area of the lightwindow 34.

Due to the provision of a second housing part 42, no housing seal 40 isrequired according to FIG. 2.

Referring to FIG. 4, a lid section 100 includes a bezel section 120 anda rim section 180 extending between a first rear view means 300 and asecond rear view means 400 arranged on the lid section 100.

The second rear view means 400 is a so called spotter having a widerfield of view than the first rear view means 300. The first rear viewmeans 300 can include a reflective element in the form of a mirror glasscoated with a chrome or silver layer. However, any other known rear viewmeans can be used instead, such as a display. The second rear view means400 may be provided by a coating on chromium base applied directly onthe lid section 100.

In an example, the lid section 100 can be formed out of a polymericsubstrate with the bezel section 120 and a combined, single-piececomponent onto which the chromium-based reflective coating is applied toprovide the second rear view means. Further details on the coating isdescribed in U.S. patent application Ser. No. 15/439,188, which isherein incorporated by a reference in its entirety for all purposes.

The rim 180 can be provided with a transparent surface to which a blindspot indicator is fixed as described in U.S. Pat. No. 8,779,911 B2,which is herein incorporated by reference in its entirety for allpurposes.

Further details on the bezel section 120 are illustrated in FIGS. 5 and6. Referring to FIGS. 5 and 6, the bezel section 120′, 120″ can beprovided with an undercut 130′, 130″ for locking the lid section 100′,100″ to the respective, not shown housing section such that the insideof the head section is sealed to the outside in line with the teachingof U.S. patent application Ser. No. 15/000,754.

In this example, the lid section includes, in addition to the bezelsection, the combined, single-piece component which is to be coated witha chromium-based reflective coating to form the second rear view means400. In the following, the combined, single-piece component is referredto as second rear view means section 160′, 160″. The respective section160′, 160″ can be flat or curved. In the embodiments of FIGS. 5 and 6,the second rear view means section 160′, 160″ is flat and inclined.Between the second rear view means section 160′, 160″ and the respectivebezel section 120′, 120″, a first groove 200′, 200″ can be provided.

Still referring to the examples of FIGS. 5 and 6, the lid section canalso be provided with a first rear view means section 140′, 140″, thusforming a multi-function backing plate. In the embodiments of FIGS. 5and 6 the first rear view means is moveable together with the secondrear view means as both rear view means are moveable together with acomplete head section due to the fact that the lid section 100 is lockedto the housing section. That is, the entire mirror assembly includingthe housing, the lid, and the one or more rear view means may beadjustable inwardly, outwardly, upwardly, and/or downwardly.

The housing section can comprise two parts to facilitate the assembly ofthe head section. In addition, the housing section can have one or morelight windows as described in U.S. patent application Ser. No.15/000,754.

Even for those embodiments using a lid section which is a multi-functionbacking plate, the first and second rear view means sections 160′, 160″,140′, 140″ can be provided with different curvatures and/or withdifferent inclinations with respect to each other and/or the bezel 120′,120″.

In the embodiment shown in FIG. 5, there is a step 210′ being providedbetween the two rear view means sections 140′, 160′ such that areflective element providing the first rear view means 300′ can beattached below the second rear view means surface 140′, for example viaan adhesive.

In the embodiment shown in FIG. 6, there is not only a groove 200″between the bezel section 120″ and the second rear view means section160′, but also between the bezel section 120″ and the first rear viewmeans section 140″. In addition, a second groove 230″ is provide betweenthe two rear view means sections 140″ and 160″.

Independent of whether there is a rim 180, a step 210′ or a groove 230″provided between the two rear view means 300, 300′, 400, 400′, it ispreferred in one aspect that the first rear view means 300 be providedwith a recess 320 into which the second rear view means 400 extends, asshown in FIG. 4.

In the example illustrated in FIG. 5, the second rear view means 400 maybe provided by the chromium-based reflective coating. It is alsopossible to coat the lid section 100 not only in its second rear viewmeans section 160′, but also in its bezel section and/or its first rearview means section. The coatings might be different. In particular, adifferent color could be chosen for the coating in the bezel sectioncompared to the coating in the first rear view means section and/or thesecond rear view means section.

The rim 180, the groove 200′, the groove 220″ and/or the groove 230″ mayor may not be coated. If there is a coating, it might be different fromthe one in the bezel section and/or in the rear view means sections.

The lid section includes a polymeric substrate, which is preferablyinjection molded into the required form. The lid section may not beformed with a first rear view means section, or may be formed with afirst rear view means section which does not extend to the complete areaof the first rear view means, as for example illustrated in FIG. 7. Thatis, the lid section 100″′ may include a first rear view means section140″ which has an extension providing a second rear view means section160″, with the respective extension being sufficient for an attachmentof the reflective element of the first rear view means 300″′ for examplevia an adhesive layer 310″′. As an alternative, the first rear viewmeans does not have to be fixedly secured to the lid section at all inorder to be moveable with respect to the head section of the rear viewdevice.

With the simple lid section 100, 100′, 100″ or 100″′ of the invention itis possible to reduce the number of parts and thus the time needed forassembling the head section of a rear view device. In addition, the headsection becomes more compact. It is also advantageous to provide asealed head section in order to reduce the parts needed in connectionwith any electronic unit provided within the head section, in particularby omitting a housing of the electronic unit.

It should be appreciated that the above described head sections may beused with a movable head assembly of an external rear view device havinga base assembly 10, a frame means 20, an articulation assembly 30 and acasing 40. These parts will be described in the following descriptionwith reference to FIGS. 8-12B.

A moveable head assembly of an external rear view device is for exampledescribed in European Patent Application No. 16198759.9, which is herebyincorporated by reference in its entirety for all purposes. Thisapplication describes that a head section belonging to a head assemblyof an external rear view device, in particular in the form of a mirrorhead of an external rear view mirror, can be articulatedinboard/outboard and up/down using an articulation means, in particulara glass actuator, around a spherical joint, with spherical seats beingprovided between parts moving relative to each other such that they canrotate around two articulation axes perpendicular to each other having acommon joint point. This ensures the maintenance of current end userfunctionality while offering significant smaller mirror size, with areduction of size up to 30%. In addition, the unique layout of theinternal mechanism with its spherical seats enhances packaging andperformances.

According to European Patent Application No. 16198759.9, thearticulation assembly is also supported and protected for impact usingthe spherical seats, in particular due to the arrangement of frame meansbetween the articulation assembly and a casing of the head assembly. Thecasing being assembled from several casing elements, one of which issecured to the moveable part of the articulation assembly, improves theweight distribution and reduces total housing frontal area on thevehicle which in turn improves aero performance and, thus, provides ahigher fuel efficiency. Still further, the pivot system used for therear vision device of the invention with the single pivot point for twoarticulation axes permits a mirror adjustment movement while providingdynamic mirror performance and mirror impact support.

Referring to FIG. 8, the base assembly 1000 may include a foot 1200provided with a spherical seat 1300 from which a shaft type carrier part1400 extends, with the carrier part 1400 being provided with a cableexit 1500. The foot 1200 can be closed at its end opposite the sphericalseat 1300 by an attachment part 1100 discussed with respect to FIGS. 12aand 12b below.

The base assembly 1000 is fixedly secured to a motor vehicle (not shown)via the attachment part 1100 when in use.

FIGS. 9A and 9B depict the frame means 2000 fixedly secured to the baseassembly 1000. The frame means 2000 is provided by a support part 2100more or less with a ring shape, two spherical seats 2200 and 2500provided by extensions 2200 a, 2200 b and 2500 a and a fixation part2300 into which the carrier part 1400 of the base assembly 1000 isinserted such that the lower spherical seat 2200 in FIGS. 9A and 9B isfacing the spherical seat 13 of the foot 12. The extensions 2200 a, 2200b and 2500 a extend from opposite sides of the fixation part 2300, withtwo lower extensions 2200 a, 2200 b providing a lower spherical seat2200 and the upper spherical seat 2500 being provided by an upperextension 2500 a.

The fixation part 2300 is provided with a cable exit 2400 in alignmentwith the cable exit 1500 of the carrier part 1400. For securing theattachment of the frame means 2000 to the base assembly 1000 a screw(not shown) can be entered into a screw hole 2700 provided by thefixation part 2300 and the carrier part 1400.

As can be seen in FIG. 10A the articulation means 3000 can be attachedto the frame means 2000 by partly inserting a fixed part 3200 of thearticulation assembly 3000 into the support part 2100. The respectivearrangement can be fixed with a clip connection or the like. The fixedpart 3200 is moveably connected to a moveable part 3400 of thearticulation assembly 3000, with the moveable part 3400 facing away fromthe frame means 2000.

The lower extensions 2200 a and 2200 b provide a part ring together withthe lower part of support part 2100 to provide the spherical seat 2200,with a rim 2800 being provided by a cut-out at the end facing themoveable part 3400 of the articulation assembly 3000. The moveable part3400 is provided with attachment means 3500 in form of recesses for theattachment of a casing 4000. FIG. 10B shows the subassembly of FIG. 10Bwith a lower casing element 4200 of the casing 4000 attached thereto.The lower casing element 4200 is provided with an attachment part 4400attached to the moveable part 3400 of the articulation assembly 3000 ina fixed manner in order to move together with the moveable part 3400.For that purpose, the attachment part 4400 is formed with attachmentbosses 4500 shown in FIG. 11A, with the attachment bosses 4500 beinginsertable into the attachment recesses 3500, and with a part ring 4400a for partly encompassing the moveable part 3400 to add strength to theconnection of the lower casing element 42 and the moveable part 34 dueto an enhanced power transmission. Further ribs and the like can beadded to further increase the strength.

As can be best seen in FIG. 10B the part ring 2100, 2200 a, 2200 b andthe part ring 4400 a are complementary to each other to lead to acompromise of the spherical seat 2200 enabling a smooth movement of thelower casing element 4200 together with the moveable part 3400 on theone hand and a strong connection of the lower casing element 4200 to themoveable part 3400 on the other hand.

In addition, the lower casing element 4200 is provided with a base part4600 arranged between the foot 1200 and the frame means 2000, inparticular the lower extension of the frame means. The base part 4600 isprovided with a lower spherical seat 4700 cooperating with the sphericalseat 1300 of the foot 1200 and an upper spherical seat 4800 cooperatingwith the lowest spherical seat 2200 of the frame means 2000.Accordingly, the overall structure is that of three parts spheres withthe inner part sphere provided by the frame means 2000 and the outerpart sphere provided by the foot 1200 of the base assembly 1000 beingfixed, whereas the part sphere provided by the lower casing element4200, and being arranged in the middle can be moved around twoarticulation axes in order to provide an inbound/outboard and up/downmovement. Attached to the attachment part 4400 is a not shown mirrorglass which can thus be moved via the articulation assembly 3000 tofulfil the legal field of view requirements of the rear view mirror.

FIG. 11A provides further details of the relative arrangement of thelower casing element 4200 with respect to the base assembly 1000.

FIG. 11B shows the subassembly of FIG. 11A together with the fixed part3200 and movable part 3400 attached between the carrier part 1400 of thebase assembly 1000 and the attachment part 4400 of the lower casing4200. The articulation assembly 3000 also includes not shown drivemeans, in particular including two motors for the movement of themoveable part 3400 around the two articulation axes, and a controlsystem 3600, for the drive means which is partly shown in FIGS. 12A and12B.

The perspective view of FIG. 12A not only shows the subassembly providedby the base assembly 1000, the articulation assembly 3000 and the lowercasing element 4200, but also an upper casing element 4100 of the casing4000 and a camera 5000 both being attached to the lower casing element4200. FIG. 12B shows the subassembly of FIG. 12A from an opposite side,still without the casing 4000 closed via a non-shown additional casingelement to complete a head assembly 6000. But FIG. 12B shows in additionto the upper casing element 4100 and the lower casing element 4200 abezel 4900 attached to the upper and lower casing elements 4100, 4200.The bezel 4900 surrounds the not shown mirror glass of the completelyassembled external rear view mirror of the present invention.

Still further, the control system 3600 of the articulation assembly 3000is carried by the attachment part 1100. When the attachment part 1100 issecured to the foot 1200, the control system 3600 is completely arrangedwithin the foot 1200. Also arranged within the foot 1200 are cableswhich exit the base assembly 1000 at the cable exit 1500 and reach theinterior of the head assembly 6000 by passing also through to the cableexit 2400 of the frame means 2000 in order to be connected to the camera5000 and other non-shown units like lighting units and the like, whichare arranged within the head assembly 6000.

The head assembly 6000 or rather the mirror head as a whole can bearticulated using the articulation assembly 3000 in particular via themovable part 3400. The movable part 3400 is connected to the drivesystem which can be a part of the control system 3600. The controlsystem 3600 can also comprise memory means for memorizing a position ofthe movable 3400 and, thus, the mirror glass attached thereto via theattachment part 4400.

The support part 2100 is provided in form of an actuator ring which isclipped onto the fixed part 3200 to provide improved support in animpact situation. Due to its upper spherical seat 2500, the frameassembly 2000 is ensuring a smooth movement of the upper casing element4100 which is also provided with an internal spherical seat, not shown.

The arrangement of the support part 2100 with its extensions 2200 a,2200 b, and 2500 a providing the spherical seats 2200, 2500 relative tothe movable upper and lower casing elements 4100, 4200 provide a supportand stiffness in all three directions during dynamic and impactsituations. The result is a smaller mirror system offering the customera unique external rear view mirror weight as well as aero and vehiclefuel efficiency benefit.

Another moveable head assembly of an external rear vision device is forexample described in European Patent No. 2 492 145, which is herebyincorporated by reference in its entirety for all purposes. This patentrefers to an external rear view mirror with a mirror head and a mirrorbase. The external rear view mirror with a mirror head and a mirror baseis covered with at least one body element in the form of a body frame, abody cap and a mirror base cover, and a mirror glass that is installedrigidly relative to the mirror head. The mirror head rests on the mirrorbase, and the body cover of the mirror head is composed of multiplepieces of the body frame and the body cap. The mirror base is equippedwith a mirror base cover where the body cap has an opening designed forthe passage of the mirror base and the mirror base cover. The mirrorbase is rigidly connected to a mirror carrier that carries an electricalglass adjustment drive where the glass adjustment drive is connected toat least one body element. These parts will be described in thefollowing description with reference to FIGS. 13-21.

FIG. 13 shows a sectional view through the x-z plane in vehiclecoordinates, where x represents the longitudinal axis of the vehicle.The head section or rear view means 501 includes a base 502, which isrotatably connected to a support 503. The head 510 is thereby pivotableabout the axis 508, so that the head can be hinged in a parking positionin the direction of the vehicle. In the case of FIG. 13, an electricaldrive for the tilting movement is provided. The base 502 as well as thesupport 503 are clad with plastic covers. In the region of the mirrorbase, a mirror foot cover 505 conceals the technical design; the mirrorsupport 503 is concealed by a housing cap 506 and a housing frame 507.The mechanical connection to the outer contour 504 of the vehicle is notdescribed in detail. Since the longitudinal section of FIG. 13 extendsthrough the axis of the mirror foot, the glass adjustment drive is notvisible.

FIG. 14 shows the mirror head from FIG. 13 in a section along they-axis. On the left, the axis of rotation 508 can be seen around whichthe mirror head 510 rotates. The mirror support 503 is rigidly connectedto the housing frame 507 and the housing cap 506 and, during itsmovement against the mirror base, carries with its mirror foot coverthese housing elements. A commercial glass adjustment drive 515 ismounted on the mirror support. This drive is, for example, a drive asknown from EP 2017127, have a half-shell-shaped housing and a turntable512 which can be displaced therewith, which generally has a planarcontact surface for connecting the mirror glass 511. The mirror glass511 is held in a glass support plate 516, as illustrated in FIG. 16, oris installed on the glass adjustment drive in such a way that it can bepivoted into the desired position by means of two adjusting elements ofthe glass adjustment drive via the rotary table 512. The installation ofthe glass on the glass support plate 516 is provided for reasons offragmentation protection.

FIGS. 15A-15C show views of an aspect of the inventive solution. Themirror glass 511 is no gap between the glass and the housing isinstalled directly in the mirror head. The mirror glass 511 is notpivoted to the housing elements. The mirror glass 511 need not beenclosed or covered by a mirror glass support in this embodiment. Thesplinter protection can be guaranteed also heads by simply applying anadhesive film. The mirror head 510 is seated on a mirror 502. The casecovers the mirror head are either multipart constructed with rack 507and housing cap 506 or consist of a single component. The mirror 502 isprovided with a mirror base. 505. In one embodiment, the mirror base 505a recess 513 into which the lens of a lighting as a perimeter light, aposition light, a warning or an indicator can be integrated.

As a result of the movement, the opening 514 must be larger than thediameter of the mirror foot cover 505. The mirror head 510 moves againstthe mirror base so that the opening 514 must be adapted depending on thedisplacement movements of the mirror head. Since splashing water couldpenetrate into the mirror head through the opening 514, in anotherembodiment. it is provided to close the opening around the mirror footcover with a flexible membrane.

FIGS. 16 and 17 show the mirror housing construction without housingcovers. The mirror base 502 is integrally connected to the mirrorsupport 503′. The glass adjustment drive 515 is firmly installed on themirror support 503′. In this example, the glass adjustment drive 515 isalso a commercial drive with a hemispherical housing and a flatturntable 512. This rotary table 512 is rotated by the drive against thehemispherical housing. A mirror glass carrier 516, which carries themirror glass 511, is mounted on the rotary table 512. In an example, themirror glass carrier 516 is not only a flat plate, but is designed as aplate with a mount 518 connected thereto. The support 518 overcomes thedistance between the turntable 512 of the glass adjustment drive and themirror glass plane with the mirror glass 511.

FIG. 18 shows that the mount 518 does not have a parallel constructionbetween the turntable 512 of the glass adjustment drive and the mirrorglass 511. The turntable 512 is inclined by an acute angle a against themirror surface. For this purpose, the holder is designed as a hollowcylinder whose end faces are cut at different angles.

The mirror glass carrier 516 has clips 517 along the outer edge of themirror glass. These clips 517 are received by counterparts in thehousing cover 506 and serve for connection to the housing cover elementsof the mirror head, such as the housing cap 506 and/or the housing frame507. It does not matter here whether the housing cover is designed inone or more parts. The housing cover is rigidly connected to the mirrorglass carrier 516 and the turntable 512 of the glass adjustment drivewith the clips.

If the glass adjustment drive is activated and at least one of theadjustment elements is controlled, the turntable 512 of the glassadjustment drive 515 rotates against its hemispherical housing and themirror support 503′. With the rotary table 512, the entire structure,consisting of the mirror glass support 516, the mirror glass 511 and thehousing cover 506, rotates against the mirror support 503′ and thusagainst the mirror base 502.

FIGS. 19 and 20 show the mirror foot 502 with mirror support 503′ as aone-piece component. In this exemplary embodiment, the mirror foot 502is formed integrally with the mirror support 503′ made of metal casting.However, it is also possible to use other materials such asfiber-reinforced plastic or other special plastics. The mirror supportand the mirror foot can also be produced in several pieces and thenrigidly connected to one another. Thus, the fastening element 502′serves for mechanical connection to the vehicle, but is rigidlyconnected to the mirror foot 502 in the case of use. It is onlyimportant that no movement is possible between mirror base 502 andmirror support 503′.

In this case, the mirror base 502 is designed as a hollow cylinder inorder to allow the electrical connection to be carried out. The mirrorfoot can be configured in one or more parts. In FIGS. 19 and 20, themirror foot 502 is constructed in several parts and has an unlockingline 532 which connects the hollow cylinder 502 with the fasteningelement 502′ fastened to the vehicle. The disengagement line 532 isprovided for the emergency and allows the mirror to break off at thispoint in the event of an impact. It will be appreciated that the mirrorfoot assembly is considered to be rigid in use, and the disengagementline is not seen as a possibility of movement for use.

The mirror foot 502 opens into the mirror carrier 503′, which has beendesigned as a triangular plate 530, for example. The carrier plate 530has webs 531, which are provided as screw domes for fastening the glassadjustment drive. In order to accommodate the hemispherical housing ofthe glass adjustment drive, the carrier plate 530 has a central recess533. The semi-spherical housing of the glass adjustment drive then sitsin this recess 533 and extends into the space 534 between the webs 531.For the rigid fastening of the glass adjustment drive, however, anyother method such as clipping, pressing, welding, etc. can also beselected.

The adjustment of the mirror glass by adjusting the entire mirror headagainst the mirror base and the mirror foot cover takes place bydeflecting the two motors of the glass adjustment drive in differentdistances and thus moving the rotary table 512 with the mirror support516 and the mirror glass 511.

FIG. 16 shows the rotational axes of the glass adjustment drive with Aand B. A movement around the B axis controls the position approximatelyby the horizontal, a movement about the A axis moves the mirror headnear the vertical to or from the vehicle. This movement is performedasymmetrically in a preferred embodiment. Since the commercial glassadjustment drives are limited in the deflection and the wish is to applythe mirror head closer to the outer contour of the vehicle in a parkingposition, the mirror glass carrier plate 516 according to FIG. 18 iskeyed with the angle alpha. As a result, the outer edge of the mirrorhead can be pivoted by a greater angle than would be possible in theadjustment path of the glass adjustment drive with a parallelconstruction.

FIG. 21 shows an alternative structure of the mirror adjustment. Theglass adjusting drive 515 is installed with its surface 512 in such away that the surface 512 points in the direction of the housing cap 506.The rotary table 512 of the glass adjusting drive 515 engages eitherdirectly or via a connecting plate 517 on the housing cap, which isrigidly connected to the mirror glass 511.

The electrical connection of the external rearview mirror is effectedvia the hollow mirror base 502. The electrical cables for the glassadjustment drive are carried out and connected directly to the drive.When a heatable mirror glass is used, the contacting of the mirror glassis achieved either directly via the glass adjusting motor 515 or, in theembodiment according to FIG. 9, separate contacts are laid with theirown electrical supply line.

Another example of an external rear view mirror assembly for a motorvehicle includes a mirror base or foot provided for arrangement on themotor vehicle and a mirror head arranged on the mirror foot as well as amirror glass accommodated in the mirror head and arranged rigidly andfixed non adjustably with respect thereto. This is described in EuropeanPatent No. 2 492 144, which is hereby incorporated by reference in itsentirety for all purposes. At least one articulation is provided betweenthe mirror head and the arrangement of the mirror foot on the motorvehicle, this articulation including a total of two articulation axes,the direction vectors of said articulation axes being independent ofeach other, and where the two articulation axes are associated, jointlyand/or independently of each other. This may allow swiveling at leastthe mirror head from an operating position to a swung-in position andvice versa, and swinging-in at least the mirror head in and against thedirection of motion, as well as adjusting an individual adjustingposition of at least the mirror glass by adjusting the mirror headdepending on, e.g., the seating position and the height of a driver ofthe motor vehicle. In addition, there may be provided a first adjustingdrive driven by an electric motor and associated to a first articulationaxis of the two articulation axes and a second adjusting drive driven byan electric motor and associated to a second articulation axis of thetwo articulation axes.

Referring now to FIG. 22, rear view arrangement 601 for a motor vehicleincludes of a base 602 provided for the motor vehicle-side arrangementand a head 603 arranged thereon, as well as a viewing means 604, whichis accommodated in the head 603 and which is rigidly and fixedlyarranged relative thereto. At least one articulated joint 605, 606, 607is provided between the head 603 and the motor vehicle side of the base602.

The at least one articulated connection 605, 606, 607 includes a totalof two articulation axes 608, 609, the directional vectors which definethe positions of the two articulation axes in the space are independentof each other.

The two joint axes 608, 609 are in each case joint and/or independent ofone another. A pivoting movement at least of the mirror head 603 from anoperating position into a folding position and vice versa, a folding atleast of the mirror head 603 in and counter to the embodiment shown inFIG. 25 as indicated by the arrow F, as well as a setting of anindividual adjustment position at least of the viewing means 604,depending, for example, on the seat position and the body size of adriver of the motor vehicle.

A first electromotive adjusting drive 610 is assigned to a firstarticulation axis 608 of the two articulated axes 608, A secondelectromotive adjusting drive 611 is assigned to a second articulationaxis 609 of the two articulation axes 608. The exterior rear viewarrangement 601 includes, collectively, the viewing mean 604 as at leastone reflecting or mirrored surface, which can be viewed by a driver ofthe motor vehicle from the vehicle interior, for example, through a sidewindow and provides insight into one or more areas of a vehicleenvironment including in the direction of the road from the driver'sseat.

For example, to avoid glare by backward light sources, the viewing means604 may be a mirror glass and an electrochromic dimming of the mirrorglass can be provided. For this purpose, the mirror glass 604 can bedesigned as an electrochromatically dimmable mirror glass.

The first joint axis 608 and the second joint axis 609 can intersecteach other as shown in FIGS. 26 to 30. For example, the first joint axis608 and the second joint axis 609 intersect at a right angle, as in thecase of the embodiments shown in FIGS. 28 to 30.

Rear view arrangements 601 are provided. Alternatively, the firstarticulation axis 608 and the second articulation axis 609 can bewind-wise relative to one another as shown in FIGS. 22 to 25. One of thetwo articulated axes 608, 609 can be as shown in FIGS. 24, 25, 28 and29, and in the case of the arrangement of the rear view arrangement 601on the side of the vehicle, the rearview arrangement 601 is essentiallyapproximately vertical.

In another example, one of the two articulated axles 608, 609 can be asshown in FIGS. 24, 25, 28 and 29, and be substantially approximatelyhorizontal when the rear view arrangement 601 is arranged on the vehicleside.

Referring to FIGS. 5 and 6, it is also possible for the position of thesecond articulation axis 609 in the space, during a pivoting or pivotingmovement, to adjust about the first articulation axis 608. In order tomeet the various possible positions of the joint axes 608, 609, the twoelectromotive adjusting drives 610, 611 are preferably controllableindependently of one another.

If desired, controls commands for the first electromotive adjustingdrive 610 and for the second electromotive adjusting drive 611 aregenerated by a control device 612 which control the latter outwards bypivoting and/or adjusting around the two joint axes 608. Pivoting and/oradjusting by at least one desired pivoting axis of the imaginary axis615, 616, which is identical to the adjusting axis, is executed.

The articulated connection 606, includes the first articulation axis608, is provided for the arrangement of the mirror base 602 on the motorvehicle side. Moreover, in the case of these external rearviewarrangements 601, the articulated connection 607 between the mirror foot602 and the mirror head 603 including the second articulation axis 609is provided.

In the case of the rearview mirror arrangements 601 shown in FIGS. 29and 30, the articulated connection 605 comprising both the firstarticulation axis 608 and the second articulation axis 609 is providedfor the arrangement of the mirror foot 602 on the motor vehicle side. Inanother example, the articulated connection 605 including both the firstarticulation axis 608 and the second articulation axis 609 is providedbetween the mirror foot 602 and the mirror head 603 of the rearviewarrangement 601.

Depending on the configuration of the rearview arrangement 601, at leastone of the two electromotive adjustment drives 610, 611 can be rigidlyconnected on the vehicle side. In the embodiments shown in FIGS. 22, 24,26 and 27, the first electric adjustment drive 610 is assigned to thefirst articulation axis 608.

The at least one articulated connection 605 can be realized by a balljoint 613 as shown in FIGS. 28, 29 and 30. This has the advantage thatboth articulated axes 608, 609 are encompassed by the articulatedconnection 605 or are formed by the latter. A further advantage resultsfrom the fact that both the first electromotive adjusting drive 610 isassigned to the first articulation axis 608 and the second electromotiveadjusting drive 610 associated with the second articulation axis 609 canbe rigidly connected on the vehicle side.

The ball joint 613 can be provided, as in FIGS. 29 and 30, for thearrangement of the mirror base 602 on the vehicle side, or as shown inFIG. 28 for producing the articulated connection 605 between the mirrorhead 603 and the mirror base 602. In FIG. 28, the mirror base 602 isrigidly arranged on the vehicle side or is provided to the rigidvehicle-side arrangement.

Referring to FIGS. 22-27, the rearview arrangement 601 can accommodate arepeat flashing light 614, for example, in the mirror head 603.Depending on the configuration, the rear view mirror arrangements 601can be mounted on a door brace 617 (FIGS. 22-25 and FIGS. 28-30),preferably from a substantially vertical vehicle surface 618. The rearview assemblies 601 may provide a standing or hanging arrangement of thehead 603 on the base.

The rearview arrangement shown in FIG. 30 shows a particular embodiment.In this case, the head 603 can be completely covered by the viewingmeans 604, and can be a part of the viewing means 604, or encompass it.

Further to the above described examples, preferred dimensions for theradius of curvature may vary between the curved mirror or rear viewmeans and a substantially flat mirror or rear view means. For example,to achieve a wider field of view, the curved mirror may have a radius ofcurvature that is between 0 mm and 1,300 mm. The flat mirror may beentirely flat or may be slightly curved having a significantly largerradius of curvature. In addition, a flat mirror includes a mirror whichprovides a user with a one to one ratio of magnification. That is, theviewed image may be the same dimensions as the actual image with a 2%plus or minus degree of distortion.

In addition, as described in multiple embodiments above, the curvedmirror may be tilted with respect to the flat mirror, or the flat mirrormay be tilted with respect to the curved mirror. Also, both mirrors maybe selectively adjustable by an actuator or manually by a user, beingboth adjustable together and separately with respect to one another. Thepreferred positions for the angle of the one mirror, for example thecurved mirror, with respect to the other mirror, for example the flatmirror, is between +40 degrees and −40 degrees outwardly, inwardly,upwardly, or downwardly. As used herein, the terms outwardly refers totilting the mirror away from the door of the vehicle, inwardly refers totilting the mirror toward the door of the vehicle, upwardly refers totilting the mirror toward the sky, and downwardly refers to tilting themirror toward the surface of the road.

The rearview device can also be equipped with different illuminationdevices.

Referring to FIGS. 31A and 31B, due to the movement of the head assembly6000, a non-moving area for securing a camera 62 may be used. In thisexample, the camera 62 is positioned in a solid, non-moving area whichdoes not move when the head actuates. FIGS. 31A and 31B show the camera62 located in the mirror base assembly 61 fixed on the base frame 65with a camera connector 66. The camera 62 is covered by a base cap 63and the base assembly is covered by a base cover 64 and secured via agasket 67 to a motor vehicle (not shown). FIG. 31B illustrates a sectionview along the line 6 b-6 b of FIG. 31A. In this example, the camera 62is fixed in the mirror base assembly 61 of the rear view means.

In another example, the camera may be fixed to the head assembly 6000.As shown in FIG. 32, the camera 73 is mounted on the base frame 72 thatis connected to the base assembly 77. Attached to the base frame 72, aswell, is the articulation assembly 70 that moves the mirror headconnected via the upper cradle 71 a and lower cradle 71 b. The uppercasing element 76 a is connected to the upper cradle 71 a, and the lowercasing element 76 b is connected to the lower cradle 71 b. The headassembly is finally locked through a bezel 75 that carries the mirrorglass 80.

The camera 73 is fixed by a camera cradle 74 and is directed to viewthrough an opening in the bezel 75 through the glass 80 and/or to viewunder the mirror through a lens 78, which is installed in the lowercasing element 76 b. As in the configuration of FIGS. 31A and 31B, thecamera of FIG. 32 is secured to a solid, non-moving area that does notmove when the head actuates. The camera 73 is packaged into the caseframe of the head assembly 6000. This provides the camera 73 with anumber of different fields of view; in particular, producing at leastimages of the rear of the vehicle, the side of the vehicle, the front ofthe vehicle, or the underneath the mirror or the vehicle. In theillustrated example, the camera 73 is directed to view behind thevehicle through the glass 80 and underneath the mirror through the lens78.

Referring to FIGS. 33A, 33B, 33C, and 33D a cassette bezel 81 a, 81 b,and 81 c may be used in combination with the head assembly 6000described throughout this application. The head unit may be suppliedwithout the glass, bezel, or scalp being attached, thus allowing forlate configuration and adjustability by the customer. There are a numberof different ways that the cassette bezel 81 a, 81 b, 81 c may beattached, as illustrated in FIGS. 33A, 33B, and 33C. Different glass 80types may be attached to the head assembly in a removable way andprovide the final locking system to control the head assembly retentionand alignment of the mirror head. Different substitutable glass typesinclude, but are not limited to, standard glass or EC glass. Differentsubstitutable bezel types include, but are not limited to, standardbezels or bezels including lighting elements and functionalities.

The cassette bezels 81 a, 81 b, 81 c are single, unitary parts and theyare first latched over the lower casing elements 84 a, 84 b, 84 c and/orrespectively partly in combination with the lower cradles 86 a, 86 b, 86c. Once latched to the lower casing elements 84 a, 84 b, 84 c, thecassette bezels 81 a, 81 b, 81 c are then rotatable about the lowercasing elements 84 a, 84 b, 84 c almost as if hingedly attached. Thecassette bezels 81 a, 81 b, 81 c then tilt into the upper cradles 85 a,85 b, 85 c, to also lock to the upper casing elements 83 a, 83 b, 83 c.FIG. 33D best illustrates the cassette bezels 81 a, 81 b, 81 c asattached to the lower casing elements 84 a, 84 b, 84 c and before beingtilted to attach to the upper casing elements 83 a, 83 b, 83 c.

Referring back to FIGS. 33A, 33B, and 33C, the linking portion of thebezels 81 a, 81 b, 81 c which attaches to the lower casing elements 84a, 84 b, 84 c may have at least three different configurations includingtapered square male-female attachment, as in FIG. 33A, tapered squaremale-female attachment with an extended support area, as in FIG. 33B,and a curved attachment with an extended support area, as in FIG. 33C.Also, the linking portion of the bezels 81 a, 81 b, 81 c which attachesto the upper casing elements 83 a, 83 b, 83 c may have at least threedifferent configurations such as a tapered projection extending throughthe upper cradle 85 a, as in FIG. 33A, a rectangular projectionextending only partly into the upper cradle 85 b, as in FIG. 33B, or arectangular projection extending through the upper cradle 85 c. A numberof other configurations can also be used and the invention is notlimited to these configurations.

FIGS. 34A, 34B, and 34C are diagrams illustrating a support mechanismfor the articulation assembly inside the head assembly. As thearticulation assembly 90 is the mechanical fixing point between themoving mirror head and the fixed base, it needs protection from downwardload exerted on the mirror head. It should be noted that theconfiguration of the articulation assembly 90 in this example isopposite to the example illustrated in FIGS. 8-12B. That is, the movingpart of the articulation assembly 90 of this example is the sphericalportion having the larger diameter shown on the left hand side of thedrawing, and the non-moving part of the articulation assembly 90 is thefixed part with the smaller diameter shown on the right hand side of thedrawing. As can be seen in FIGS. 34A, 34B, and 34C, additional supportis provided by a bracket mounted on the fixed base frame 93 hugging thearticulation assembly 90 with two elongated hole rings, one on eachopposite side of the articulation assembly 90. Through the holes anupper cradle 91 mounted on the articulation assembly 90 and a lowercradle 92 mounted on the mirror head are joined to each other allowingrotational movement inboard/outboard and up/down. The elongated holecase frame rings create the locking mechanism and provide the inboardand outboard stops.

FIG. 34B is a cross-sectional view showing the attachment of the uppercradle 91 to the lower cradle 92 and the hole of the base frame 93 alongthe line 9 b-9 b of FIG. 34A. As shown in FIG. 34B, the upper cradle 91and lower cradle 92 are fixedly attached and move together to one end orthe other end of the hole of the base frame 93 as the mirror is actuatedto move inboard or outboard. Referring to FIG. 34C, a cross-sectionalview showing the attachment of the upper cradle 91 to the lower cradle92 along the line 9 c-9 c of FIG. 34A is illustrated. As the mirror isactuated to move up or down, the upper cradle 91 and lower cradle 92move together within the hole of the fixed base frame 93. The base frame93 is thus a fixed surface which acts to cover the articulation assembly90 and encompass the articulation assembly 90 to support downward orother types of load.

FIG. 35 is a diagram illustrating a top down section view of the headassembly depicting the various head conditions achieved by a single 2axis articulation assembly. A park fold position of the mirror headassembly 700 can be provided using the same articulation assembly 701that is used to set the mirror in drive condition with a single 2 axisglass actuator orientated to utilize the full angular working range, asillustrated in FIG. 35.

In another example, FIGS. 36A and 36B show an assembly with 2 singleaxis actuators 704 and 705 positioned independently of each other, alongthe mirror head rotational axis, controlled by integrated memorycircuits or a separate memory module 706. Referring to FIG. 36B, across-sectional view along the line 11 b-11 b of FIG. 36A is shown withthe two independent single axis actuators 704, 705 also illustrated. Thetwo independent actuators allow the mirror to be adjustedinboard/outboard and up/down according to the desire of the driver. Aswith the articulation assembly described throughout this application,the two independent single axis actuators 704, 705 are also configuredto allow adjustment of the mirror between an outboard drive condition, astandard drive condition, a park condition, and conditions therebetween.

FIG. 37 is a diagram illustrating a plan view of a fixed glass mirrorassembly with the mirror head in the drive position on the left side andthe mirror head in the fold position on the right side.

Referring to FIG. 37, a ‘fold’ position/angle can be customer bespoke byutilizing an integrated memory sensors (not shown) within the glassactuator. For example, pre-set mirror positions can be programmedoffering flexibility of the nominal head angles to meet multiple set upconditions. In an example, pre-set mirror angles can be programmed atthe point of assembly. The individual pre set memory function may remainfunctional for all users. This allows for increased versatility infolding functionality of the side-view mirror. Accordingly, the endcustomer has the ability to determine the power fold stop position. Thisis achieved using a memory positioning function system within theactuator which is commonly used to set-up each individual driver'spreferred positions, and can further be used to set bespoke mirror fold& park positions so that the position of the mirror once parked can beset to each users' preference.

FIGS. 38A, 38B, and 38C are diagrams illustrating a fixed glass mirrorassembly with a combined side turn indicator module and blind spotmonitor module as a common assembly.

Referring to FIG. 38A, a Side turn indicator (STI) and Blind SpotMonitor (BSM) are provided as a single lighting module as opposed tobeing two separate lighting modules. The mirror is provided with a glass800 and a bezel 801. Also illustrated in FIG. 38A is an outside view ofthe indicator or light for the Blind Spot Monitor 802 provided in theglass 800 and the Side Turn Indicator 803 at the side of the bezel 801.With the fixed glass mirror assembly the relationship of the BSM moduleto the STI module is now fixed so this allows for the two modules tobecome one common assembly.

FIGS. 38B and 38C illustrate the details of the combine STI and BSMmodules. The STI and BSM modules are combined into one smaller moduleassembly, which may be integrated into the case lower component.Combining the two modules gives the option to control them with the sameor separate PCB/light sources. This also provides lower manufacturingcost, fewer parts and a more simple system that provides system &performance advantages. Referring to FIGS. 38B and 38C, the internalcomponents of the combined STI and BSM module 804 is illustrated and aconnecting rib 805 is provided between the BSM portion and the STIportion of the combined module. A cross section further illustrating theinner potion and connection of the combined module with the bezel 801and the glass 800 is provided in FIG. 38C.

FIGS. 39 and 40 are diagrams illustrating an actuator having motor jacksof different lengths to allow for increased horizontal axis movement anddecreased vertical movement.

Referring to FIG. 39, motor jacks 900A, 900B are provided in unequallengths in order to allow for increased horizontal axis movement anddecreased vertical movement within the same packaging space.

Increased rotation or movement on one axis only of a normal glassactuator allows fulfillment of power fold movement for a fixed glassmirror. The extended horizontal movement, in other words, the in/outmovement of the mirror allows the use of a single actuator without theneed to have an additional dedicated folding actuator unit to fulfil thefold & park function within the mirror. This provides the advantage ofhaving a single actuator providing the function that two actuatorstypically provide, i.e. removing the need for a dedicated actuator toposition the mirror in the park position. In an aspect, advantagesinclude replacing the noisier power fold actuator which is typicallyused for the fold and park function, allowing the smaller fixed glassmirror to be reduced in size permitting smaller mirrors on cars andreducing vehicle drag values reducing CO2, as well as reducingmanufacturing costs. The longer horizontal travel of the mirror allowsapproximately an additional degree of movement which is a completemovement that satisfies market requirements; for example, 14 additionaldegrees are enabled.

FIG. 40 provides a detailed view of the single actuator which providesan extended horizontal glass actuation and a reduced vertical glassactuation. A cross-section along the axis A-A and the axis G-Gillustrating the extended and reduced angles of travel for mirroractuation.

FIG. 41 is a diagram illustrating attachment of a motor cradle 912 and alower case 910 of a rearview device via turn and snap connectivity.

Referring to FIG. 41, a quick assembly rearview device is illustratedwhich includes a motor cradle 912 and a lower case 910. The motor cradle912 is attached to the lower case 910 and configured to receive anactuator assembly which is described in more detail below. Theattachment mechanism is a quick and easy attachment mechanism requiringa first step of placing the motor cradle 912 above and on top of thelower case 910 as shown by the large down arrow. A second step involvesturning the motor cradle 912 so that the cradle projections 912 a of themotor cradle 912 engage the tab vertical fixation lugs 910 a of thelower case 910. This is referred to as turn and snap connectivity.

As assembly as described herein allows both the motor cradle 912 and thelower case 910 to be fixed and located around a central axis (pivotaxis) and onto a common plane. This will reduce the tolerance stack backto the motor rotation center and components.

FIG. 42 is a diagram illustrating attachment of an actuator assembly 914and the motor cradle 912 of the rearview device of FIG. 41.

Referring to FIG. 42, the actuator assembly 914 is configured to actuatethe movement of the rearview device in accordance with the examplesdescribed throughout this application. The actuator assembly 914 isconfigured to easily and quickly attach to the motor cradle 912 bypushing the actuator assembly 914 in a receiving portion of the motorcradle and engaging cradle teeth 912 b into corresponding gaps betweenteeth (not shown) of the actuator assembly 914. Thus, the cradle teeth912 b fit in gaps between teeth (not shown) of the actuator assembly914, and the teeth (not shown) of the actuator assembly 914 fit inbetween the gaps between the cradle teeth 912 b.

Such an attachment prevents rotation of the actuator assembly 914 in themotor cradle 912. Small clips may also be used to keep the actuatorassembly 914 fixed with respect to the motor cradle 912 before a cradleclamp 916, described below, is fitted.

FIG. 43 is a diagram illustrating attachment of a cradle clamp 916, themotor cradle 912, and the actuator assembly 914 of the rearview deviceof FIG. 41.

Referring to FIG. 43, a cradle clamp 916 may be attached to the motorcradle 912 and actuator assembly 914 to clamp the actuator assembly 914to the motor cradle 912. The cradle clamp 916 should first slide betweenthe actuator assembly 914 and a front portion of the motor cradle 912,as illustrated by the down arrow in FIG. 43. This results in clamp prong916 b and clamp cam 916 a engaging the front portion of motor cradle912. This engagement is described in more detail with reference to FIG.44. Subsequently, the cradle clamp 916 should be rotated towards theactuator assembly 914 until clamp clips 916 c are engaged withcorresponding retaining projections (not shown) on the motor cradle 912.This also causes rotation of the clamp prong 916 b and clamp cam 916 auntil the clamp clips 916 c are engaged and the actuatory assembly 914is clamped to the motor cradle 912.

FIG. 44 is a diagram illustrating a cross-section of the cradle clamp916 at detail A of FIG. 43 after engagement with the motor cradle 912and the actuator assembly 914 of the rearview device of FIG. 41.

Referring to FIG. 44, a detailed view of a cross-section of the clampprong 916 b and clamp cam 916 a in the portion between the actuatorassembly 914 and a front of the motor cradle 912 is shown. The clamp cam916 a may be a curved projection with a corresponding receiving portionon the motor cradle 912 to allow rotation of the cradle clamp 916. Thisallows rotating the cradle clamp 916 shut until the clamp clips 916 care clipped onto the motor cradle 912 from the top. Clamping pressuremay be tuned to provide increased loading.

FIG. 45 is a diagram illustrating a cross-section of the cradle clamp916, the motor cradle 912, and the actuator assembly 914 of the rearviewdevice of FIG. 41 after attachment.

After assembly of the cradle clamp 916, the motor cradle 912, and theactuator assembly 914, a cross-section illustrates that all threecomponents of the rearview device are securely attached. Once theactuator assembly 914 is located and the cradle clamp 916 is engaged,the motor cradle 912 and an adapter ring of the actuator assembly 914combine to improve stiffness, as illustrated in FIG. 45.

FIGS. 46 and 47 are diagrams illustrating attachment of a light modulesuch as a side turn indicator (STI) module 918 with the lower case 910of the rearview device of FIG. 41. Although an STI module 918 isdescribed, any other light module for other functions may be used.

Referring to FIG. 46, the STI module 918 is first pressed down onto thelower case 910 of the rearview device. As a result, the STI tab 918 aengages the tab receiving portion 910 b of the lower case 910, and thevertical control tabs 910 c are engaged. Once fully pressed down ontothe lower case 910, the STI module 918 can be slid along a curved edgeof the lower case 910 until one or more retaining clips 918 b of the STImodule 918 are engaged.

FIG. 47 illustrates that once slid into place, the STI module 918 islocked in position. The STI module 918 to lower case 910 gap includes aseries of tabs along the lower case which allow locking of the STImodule 918 in place. In other example, the cradle clamp 912 can be usedto lock the STI module 918.
